In hot climate countries, the effects of the sun shining on the building envelope – mainly the roof – causes scolding heat to penetrate the building and transform it into a sweatbox where people find it uncomfortable and difficult to work or live.
The most obvious and seemingly easiest way to overcome this problem is to use air conditioning to maintain the indoor temperature and comfort level. But the real solution can be found by improving the building envelope to better withstand the heat and prevent it from penetrating into the building; that is minimizing heat transfer. There is also another positive effect – of trapping the cold air inside the building, thus keeping the indoor temperature cooler for a longer period.
This can be achieved by using mineral wool insulation, which should be installed below the roof, on the ceiling and facade of the building.
